In

practice I have found one-inch-an-d-a-half opening of the breast-boardto be very satisfactory in ginning Indian cotton, which is a shortstaple and small-seeded cotton. With American cotton it will bedesirable to increase the extent of the opening and possibly thefrequency of the openings, owing to the larger size of the seed, and inorder to be ableto vary the extent of such opening of the breast-boardD,I make the connection of the lug m to the bar M adjustable, so that byshifting the lugm on the bar M the length of time of its engagement withthe lug Z on the wheel G may be varied, and consequently the extent ofmovement of the bar M and of the breast-board D will be varied. Themeans for effecting the adjustment of the lugm may vary, and asillustrating one means I have shown the lug m as being provided with a'threaded stem 10, extending through a slot 11 in the bar M and providedwith a clamping-nut 12; but I do not limit myself to this special meansof adjustment.
